Many people have a hard time differentiating between venomous and poisonous creatures. While both involve a toxic substance, venomous and poisonous creatures pose a different type of harm. Venomous animals have evolved a specialized structure for delivering their toxins, while poisonous animals may require direct contact to spread their poison. In this article, we will discuss the difference between venomous and poisonous animals and creatures.

Difference Between Venomous and Poisonous

What Does Venomous Mean?

Venomous creatures must have a specialized toxic delivery system in order to be classified under this category. Examples of venomous creatures include snakes, spiders, stingrays, Jellyfish and bees. Venomous animals create and use toxins to protect themselves in both offensive and defensive situations. Venom is usually injected through a bite or a sting, which is why venomous creatures often display warning colors and patterns.

What Does Poisonous Mean?

Poisonous creatures are a distinct category from venomous creatures. These animals don’t have specialized structures for delivering their toxin, meaning contact with the poison is often necessary for it to have an effect. Poisonous creatures can be both plants and animals. Poisonous animals tend to not have warning signs to protect themselves as they are, themselves, the poison. Some example of poisonous animals are toads, salamanders and some fish. Poisonous plants such as a Poison Ivy or Hemlock, or even mushrooms can also produce harmful toxins when eaten.

Venomous vs. Poisonous

The key difference between venomous and poisonous creatures is how they deliver their toxins. Venomous creatures have evolved a specialized structure such as a fang, stinger or toothed jaw to deliver their venom into a host. Poisonous creatures, on the other hand, spread their toxin through contact in the environment. Venomous and poisonous creatures both pose a severe threat if the proper precautions are not taken while interacting with them.

Where Do Venom and Poison Come From?

Both venom and poison are biotoxins. Biotoxins are usually created by creatures in order to protect themselves from predators and competition. Venomous and poisonous creatures manufacture these toxins as a defense mechanism, either stored inside of them (venomous) or spread around them (poisonous).

Are All Venomous Animals Reptiles and Insects?

No, not all venomous creatures are reptiles and insects. There are a number of marine creatures that are also venomous, such as certain types of fish, jellyfish and stonefish. Venomous mammals are also not unheard of, such as the solenodon which is a mammal indigenous to Cuba and Hispaniola.

How Are Venomous Animals Studied?

Venomous animals are typically studied through keeping specimens in a lab or out in the wild. For some species, such as snakes and jellyfish, venomous specimens can be collected from an individual without causing major harm. If a specimen is too dangerous to collect, then scientists may use indirect methods such as genetic analysis to study them.

Are Venomous Animals and Plants Different?

While venomous and poisonous are both biotoxins, plants and animals use the toxins in different ways. Venomous creatures use their venom to subdue or kill prey, usually injecting through a bite or sting. Poisonous plants, on the other hand, produce their toxins to ward predators off or protect them from herbivores. The toxins of poisonous plants are more typically absorbed through contact with the skin or eaten.

Are jellyfish venomous or poisonous?

Jellyfish are both venomous and poisonous. They possess specialized stinging cells on their tentacles and bell which can inject venom into unsuspecting prey, while their body itself produces a toxin which can be absorbed through contact with the skin.

Final Words

The key takeaway from this article is that venomous and poisonous creatures have different means for delivering their toxins. Venomous animals have a specialized structure for delivery and poisons typically spread through contact. It’s important to be aware of the distinction when exposing yourself to potentially dangerous creatures.
